How it works
Get started in 3 simple steps.
Describe Your Content
Upload an image, paste a URL, or describe your post topic. AI understands context to write relevant captions.
Select Platforms & Tone
Choose which platforms and select a tone — playful, professional, educational, or promotional.
Generate, Edit & Schedule
Review AI-generated captions, make any edits, then schedule directly to your content calendar.
Who uses it, and for what
The photo is usually the easy part. What stops a post from being published is the twenty minutes spent staring at an empty caption field, and that friction is what turns a daily habit into a monthly one.
The visual creator
The problem. You shoot constantly and post rarely, because the caption is the tax on publishing and you keep deferring it.
With Pulpi. Captions arrive with the image, in your register. Publishing stops being a writing task and becomes a choosing task.
The brand with a strict tone
The problem. Captions are written by several people and the voice wanders, which is exactly what a brand guideline was supposed to prevent.
With Pulpi. One voice profile applies to every caption regardless of who is on shift. Guidelines stop being a document nobody opens and become the default output.
The account posting across platforms
The problem. The same caption goes everywhere, which means it is slightly wrong everywhere: too long for X, too flat for Instagram, too casual for LinkedIn.
With Pulpi. One idea, adapted per platform in length and register, without writing it four times.
What people ask before switching
Will the captions sound like everyone else's?
Generic prompting produces generic captions, which is the sludge you see everywhere. Pulpi writes from your previous posts, your audience and your offer instead of from a template, and the difference is immediately visible. You edit anything that still misses.
Does it add hashtags automatically?
It proposes them, mixing broad and niche tags for the platform in question, and you keep or cut them. Hashtag strategy differs enough between Instagram, TikTok and LinkedIn that a single set would be wrong on at least two.
Can it write in my language?
Yes, natively rather than by translating English. A translated caption reads as translated, which is worse than a plainer caption written directly in the target language.

Frequently Asked Questions
Does the AI caption generator work for all social platforms?
Yes. Pulpi.ai generates platform-specific captions for Instagram, X (Twitter), LinkedIn, TikTok, Facebook, YouTube, and Pinterest — each adapted to the platform's style and character limits.
How does brand voice training work?
During onboarding you share your brand profile — tone, audience, industry, and sample content. Pulpi.ai's AI trains on this and ensures every caption sounds like it was written by your team.
Can the AI generate captions in multiple languages?
Yes. Pulpi.ai supports 20+ languages. You can generate captions in a different language per platform, useful for brands with regional audiences.
Can I use the caption generator without scheduling?
Absolutely. Copy captions directly for use anywhere — your website, email newsletter, or manual posting. You're not required to schedule through Pulpi.ai.
Can it write captions for images I upload?
Yes. It reads the image and combines what it sees with your brand context, so the caption refers to the actual photo rather than to a generic subject.
How long should a caption be?
It varies by platform and the generator adapts: short and punchy for TikTok, room for a story on Instagram, more structure on LinkedIn.
Can I keep a library of captions that worked?
Yes. Saved captions can be reused or used as examples, which sharpens the voice over time.
